Help, I think my compilers are broken

[timothy@smasher.rs.itd.umich.edu]

All of a sudden when trying to compile stuff I get weird errors.
Eg:
g++ helloworld.cc -o hello gives
/usr/bin/ld: cannot open -lstdc++: No such file or directory
collect2: ld returned 1 exit status

(Where helloworld.cc is 
#include <iostream.h>
void main(void)
{ cout << "Hello World!"; }     )

My relevant packages are:
ii  g++             2.91.58-5      The GNU (egcs) C++ compiler.
ii  libg++27        2.7.2.1-14.4   The GNU C++ libraries (ELF version).
ii  libg++272       2.7.2.8-0.1    The GNU C++ libraries (libc6 version).
ii  gcc             2.7.2.3-5      The GNU C compiler.
ii  libc6-dev       2.0.7u-6       The GNU C library version 2 (development fil
ii  libstdc++2.8    2.90.29-2      The GNU stdc++ library (old egcs version)
ii  libstdc++2.9    2.91.60-1      The GNU stdc++ library (egcs version)
ii  libstdc++2.9-de 2.91.60-1      The GNU stdc++ library (development files)

Any ideas where I should start trying to fix this?
